Male and female cellar spiders may be found in climate-controlled structures year-round. Cellar spiders build irregular messy webs and are highly sensitive to vibrations and will close in on an unsuspecting insect rapidly if it happens to wander into its web. Indoors, they are often found in damp cellars, basements, crawl spaces, garages, and dark, quiet places. In nature, cellar spiders usually live in the openings of caves, or crevices in cliffs, and other protected places. Cellar spiders are the natural enemy of large house spiders that live in homes, and will also feed on flies, bees, wasps, and even other cellar spiders when food is scarce. These spiders can be seen in corners and ceilings, usually hanging belly-up. Some species of cellar spiders are very common in homes, especially in garages, basements, and cellars, hence the common name. They are sometimes referred to as daddy longlegs spiders, which are quite different and unrelated. Cellar spiders are inconspicuous, harmless, fragile spiders with extremely long, thin legs.
